I've spent that last four days in hospital with Covid-19 of the colon - dramatic when it started but tedious thereafter. This thread hasn't gone all that well. John Larkin has ignored the fact that I was talking about just the 3096. There have been some sensible comments, but I'm still too sick to try and provide any kind of summing up of the sensible bits. -- Bill Sloman, Sydney -- This email has been checked for viruses by Norton antivirus software. www.norton.com
